摘　　要：对现有的影像拼接缝消除方法的优缺点进行了分析,提出了基于直方图匹配的拼接缝消除方法,并用云南省范围的影像进行了试验。结果表明:直方图匹配方法可以较好地消除CBERS-02B CCD影像镶嵌时产生的拼接缝,并使其色调基本保持一致。The task of gray seam-line removal is very important in the Image mosaicking.The purpose of the paper lies on the removal of the gray seam-lines in the mosaicked image,the advantages and disadvantages of existing methods such as"wavelet trans- form method","overlapping-image method",and"hard correction method"is analysed,and then the histogram match method is presented and tested using real image of CBERS-O2B CCD in the Yunnan province.The result indicate:the method of histogram match can effectively remove...
